M ETALLIC MAT.

SPECIFICATION formingpart of Letters Patent No. 740,478, dated October6, 1903.

Application filed October 1. 1902.

companying drawings, forming part of this specification, in which'Figure 1 is a top plan view showing one form of my improved mat. Fig.2.is a detail view showing a portion of one of the strips forming themat. Fig. 3 is a longitudinal section of the mat. Fig. 4 is a partialtop plan view of another form of my mat. 'Fig. 5 is a partiallongitudinal section, partly. broken away, of the form of Fig. 4; andFigs. Sand 7 are detail views of the connecting-strips employed.

My invention relates to that class of metallic mats wherein metal stripsor ribbons are employed,which are held so that the shoes contact withtheir edges, and is designed to improve the structure of mats of thischaracter which can be rolled up.

In the drawings, referring to. the form of Figs. 1, 2, and 3, 2 2represent metallic strips or ribbons,each of which is of the shape shownin Fig. 2. As shown inthis figure, this strip is bent in zigzag form,with a portion 3 of each leg twisted or bent into a plane substantiallyat right angles to the plane of the leg. In forming a mat unit two ofthese strips 2 are interwoven with each other, the flattened portions ofone passing alternately over and under those of the other, and betweenthese flattened portions 3 I insert connecting-pieces of the form shownin Figs. 6 and 7. Each of these pieces 4 has a flattened portion 5, bentgether by means of small rivets 7, extending through the overlapped endsof the connecting-pieces 4, as shown in Figs. 1 and 3. The mat may bemade of any width, according to $erial No. 125,592- [No modelthe lengthof the strips 2, or mat-sections may be secured together side by side tosecure the desired width.

The mat may receive an end finish of any desired form, though Ipreferably shape it as shown in the upper portion of Fig. 1, the innerstrip 2 of this section having its end portion 8 bent around theflattened portion of the other strip.

In Figs. 4 and 5 I show a form similar to the first form, except thatinstead of separate rivets being used to connect the mat-sectionstogether I provide a transverse wire 9, which extends through theoverlapping ends of the pieces 4 and through the sides of the mat, theends of the wire being suitably bent or peened over. In this form Ipreferably use short spiral springs 10 between the joints of theconnecting-strips to space them apart and hold them in proper position.v

The advantages of myinvention result from the strength and light weightper'square foot of the mat. The mat may be rolled up endwise andpresents an attractive appearance, while a large amount ofresisting-surface is afiorded no matter at what angle the shoe may meetit. The shape of the meshes may be varied, as may also the method ofinterweaving and connecting the sections together, and many otherchanges may be made in the form and arrangement of the parts withoutdeparting from my invention.

I claim I 1. A metallic mat having sections hinged to each other forminga flexible mat, each section having meshes formed of bent metal stripsor pieces with twisted flattened portions; substantially as described.

2. A metallic mat formed of sections which are hinged together to form aflexible mat,

each section being formed of metal strips bent to form meshes and havingtwisted flattened portions at their junctures; substantially asdescribed.

3. A metallic mat formed of parallel sections having connecting portionshinged together to form a flexible mat, each section be ing formed of aplurality of metal strips or pieces having interfitting flattenedportions lying substantially in the plane of the mat; substantially asdescribed.

4. A metallic mat formed of metal strips or pieces bent to form mesheswith interfitting fiattened portions, and connecting-pieces havin gflattened portions interfitting with those of the mesh-pieces;substantially as described.

5. A mat formed of sections, each section having meshes formed of bentangular pieces with interfitting flattened portions and connectingstripsengaging the flattened portions; the strips of one section being hingedto those of the next; substantially as described;

6. A mat formed of sections, each section consisting of two ribbons bentin zigzag form with twisted flattened portions in the legs, theflattened portions of one strip passing alternately over and under thoseof the next, and connecting-strips with flattened portions my hand.
